server left without working dns

i initialized and deployed a demo node (pc-vpn1 in HK), and at some stage (i don't have the deploy log anymore), it was left without working dns:

root@pc-vpn1:~# host -v ix.de
Trying "ix.de"
;; connection timed out; no servers could be reached
root@pc-vpn1:~# cat /etc/resolv.conf

that's bad, further deploys don't fix it cause they depend on packages that need to be installed.

i will attach a failed deploy log (after the system don't resolve anymore).

micah, assigning to you cause you did most of the unbound work.
